Specification of Letters Patent. Patented June 25, 191%.,

Application-filed December 10, 1915, Serial No. 66,126. Renewed November 20, 1917. Serial No. 203,057.

To all whom it may concern:

Be it known that 1, JOHN C. SINDT, a citizen of the United States, residing at Peetz, in the county ofLogan and State of Colorado, have invented certain new and useful Improvements in Packer-Rims, of which the following is a specification, reference being had therein to the accompanying drawing.

r This invention relates to a packer rim and i has for its object the production of a detachable packer rim which may be applied to the ordinary disk harrow by fitting the packer rim over the periphery of the disk harrow;

Another object of this invention is the production ofan eflicient sub-surface packer for efficiently packing the soil in an even and smooth condition. I

With these and other objects in view, this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and cla'imedE In the accompanying drawing Figure 1 is a side elevation of a harrow disk, showing a series of packer sections applied thereto.

Fig. 2 is a section taken on line 2-2 of Fi 1.

Fig. 3 is a central longitudinal section through one of the packer sections, showing the bridge plate carried by the outer groove thereof.

Fig. 4 is an elevation of the inner face of a series of packers, showing the harrow disk engaging groove formed therein.

Referring to the accompanying drawing by numerals it will be seen that 1 designates the harrow disk upon which are adapted to fit the packer sections 2. Each packer section 2 comprises a body portion having a concave groove or channel 3 formed upon the outer face thereof. One end of each packer section 2 is provided with a pair of spaced jaws 4 and the other or opposite end of each section is provided with a projecting tongue 5, the projecting tongue 5 of one section being adapted to fit between the jaws 4 of the adjacent section. The rivet 6 is adapted to pivotally connect the tongue 5 of one section between the jaws 4 of the adjacent section so as to permit the several sections to conform to the contour of the periphery of the harrow disk 1, as clearly illustrated in Fig. 1 of the drawings. It

should be understood that the tongue 5 of each section is reduced in width with respect to the section 2 so as to have the side edges of the packer sections extend flush with each other around the entire harrow disk. The sections 2 of the packer are adapted tofit over the edge of a harrow disk and a bridge plate 7 is secured-to one section and is adapted to overhang the opposite end section. The sections are arranged upon the disk so as-to have the ends of the chain of sections spaced from each other asillustrated in Fig. 1. The bridge plate 7 is adapted to span the space between the spaced ends and constitutes a support for the coil spring packer 8. This coil spring packer 8 is adapted to fit upon the plate 7 and within the concave grooves formed in the sections 2 and hold these sections 2 upon the harrow disk. The" coil spring 8 is formed in two sections, each section having the convolutions on one of its ends threaded into the convolutions 15 of the other section as shown in Fig. 1, to permit the tension of the spring 8 to be regulated. It should be understood that the spring 8 will hold the packer upon the harrow disk and permit the same to be adjusted according to the different size disks upon which the packer is used by the removal of one or more of the sections 2. The coiled spring 8 is provided at one end with an eye 12, which eye is. adapted to be engaged by the hook 13 of the opposite end of the spring for firmly holding the coiled spring within the groove 3. It should be understood that the convolutions of the 'coiled spring 8 will project beyond the outer periphery of the several sections 2 as illustrated in Fig. 1 of the drawing.

It should be further understood that the beveled faces 14 of the sections 2 will constitute an efficient packer surface for the outer surface of the soil over which the packer is passing.

The sections 2 are provided with registering channels 15 which registering channels are substantially V-shaped in cross section for the purpose of permitting the sections 2 to conveniently fit over the periphery of the harrow disk 1. j

From the foregoing description, it will be seen that a very simple and efficient means has been produced for facilitating the quick and efiicient attachment of a packer to a harrow disk and in actual use seventeen of be understood that any suitable or desired number of sections may be so employed without departing from the spirit of the invention. It of course should be understood that it is first necessary to remove the scraper fromthe harrow disk before applying the packers to the disks.

What I claim is l. A detachable packer rim comprising a plurality of hingedly connected similarly constructed sections, said sections provided with concave grooves formed upon the outer faces thereof, and a coiled spring fitting within said concave grooves and extending around the periphery of said sections and projecting beyond the outer edge of said sections for producing a sub-surface packer.

'2. A detachable packer of the class described comprising a plurality of hingedly connected similarly constructed. sections, each section provided with a reduced tongue at one end and a pairv of spaced jaws at the other'end, the reduced tongue of one section adapted to fit within the spaced jaws of the adjacent section, said sections provided with a concave groove upon the outer faces thereof, a sub-surface packer seated within said concave grooves and each section provided with 'a harrow disk receiving groove formed upon the inner face thereof for permitting the connection of said packer Copies of this patent may be obtained for (siections around the periphery of a harrow isk.

3. A detachable packer of the class described comprising a plurality of hingedly connected similarly constructed sections, each section provided with a reduced tongue at one end and a pair of spaced jaws at the other end, the reduced tongue of one section adapted to fit within the spaced jaws of the adjacent section, said sections provided with a concave groove upon the outer faces thereof, and a sub-surface packer seated within said concave grooves and each section provided with a harrow disk receiving groove formed upon the inner face thereof for permitting the connection of said packer sections around the periphery of the harrow disk.

4. A packer of the class described oom prising a plurality'of similarly constructed hingedly secured sections constituting a chain-like structure having its ends spaced, a bridge plate spanning said spaced ends, a sectional coil spring carried by said sections, said sections having the convolutions on one end thereof threaded into the convolutions onthe adjoining end of the other section for permitting the tension of said spring to be adjusted, and means for connecting the other ends of said sections.

In testimony whereof I hereunto afi'ix my signature.
